Trait std::convert::TryInto

1.34.0 · source ·
pub trait TryInto<T>: Sized {
    type Error;

    // Required method
    fn try_into(self) -> Result<T, Self::Error>;
Expand description

An attempted conversion that consumes self, which may or may not be expensive.

Library authors should usually not directly implement this trait, but should prefer implementing the TryFrom trait, which offers greater flexibility and provides an equivalent TryInto implementation for free, thanks to a blanket implementation in the standard library. For more information on this, see the documentation for Into.

Implementing TryInto

This suffers the same restrictions and reasoning as implementing Into, see there for details.
